304 vr calais 5.0l conversion no spark?

I assume if you probe the blue wires on the injector side of the white plug then you get power? it might be some half baked anti theft ****.
cut that white plug crap and yellow and green joined on wires out of the loom and rejoin the blue wires to D15 and 16, doesnt matter which way round, the V8 pulses both at once anyway.

the ecu earths the injectors internally with transistors thru D15 and D16 not sure what else you want to know about that?

olds kool and you know it.

the relay for the injectors and coil and module may be turning off when cranking if powered by the wrong wire bridge the relay pins with a peice of wire so it gets constant power to the coil then crank it

 

[aidanhq]

which pins do i bridge? 30 and 85? 30 and 87?

 

[delcowizzid]

87 and 30 i think look on the relay will show you which ones is the switch part

 

[Jayme]

hahahahahah I think I just realised the problem... you have it connected to Accessories, which gets turned off while cranking. break out your multimeter and find a wire that gets power when you turn to IGN and keeps it when you hit the starter.

olds kool and you know it.

 

[delcowizzid]

feed that to the relay to trigger it

 

[Jayme]

nar you will never get 12V while cranking, it will be a combination of the starter load + batt flattery, in any case thats the wire you need hopefully youll hear the sweet sound soon
